BirdshaveUVlightnecessary for various aspects of theirhealthand behavior, including: Improved vision and color perception:Birdssee colours, including UV, that are invisible to humans. This helps them recognise food and mates.

Lightforbirdsis important to theirhealthand well-being, and there are several factors to consider.Indoor full-spectrumlightsforbirds. Not only dobirdssee a larger portion of the color spectrum than we do (they’re able to seeultravioletlight), but they also seelightfaster than we do.
UV(Ultraviolet)Lightrefers to the region of the electromagnetic spectrum between visiblelightand X-rays, with a wavelength falling between 400 and 10 nanometers.
Ultraviolet(UV)lighthas shorter wavelengths than visiblelight. Although UV waves are invisible to the human eye, some insects, such as bumblebees, can see.
